This paper determines the main influence factors on the experiment of adsorption of U(VI) by Pseudomonas aeruginosa loaded by nano- Fe3O4 (NFPA) through gray correlation analysis, based on the experimental design on adsorption of U(VI) by Pseudomonas aeruginosa loaded by nano-Fe3O4. Results show that the method is simple, objective, reliable, and providing a scientific basis for experimental design to treatment the wastewater con...
